AF MASA

AF MASA mats seal electrical cable penetrations inside cable trays.

AF MASA are recommended wherever there is a need to create a barrier that can be easily removed and re-positioned which allows a perfect seal to "cold smoke" using its permanent elasticity (sponge effect).

AF MASA are suitable for applications on floors, as they do not require supporting structures. Cut properly, they can be used instead of classic fireproof bricks.

AF MASA is a spongy parallelepiped which is easily shaped to seal openings between adjacent compartments which confine the fire to its point of origin.

When exposed to fire at a temperature that exceeds 200°C, AF MASA expands and physically modifies itself to form a highly insulating non-combustible mass.
